S6 Driver side bank not firing

Im working on a 2002 S6 which came to me not running. Replaced the Passenger side head due to bent valves and she fired up but running very rough. Im getting misfire codes on the Driver side bank and doesn't seem to be getting ignition and fuel. The codes I'm getting are: P0300, 308, 208, 205, 206, 207, 306, 305....Pretty much the entire driver side bank. EPC light is also on.
I could really use your advice. TIA!

Kinda looks like you used a generic OBD code reader. You should try a VAG Com specific reader to get more detail, something like RossTech.

Not firing or misfiring? Big difference.
How did the valves get bent on the other bank? I'd leakdown test the whole engine.

Generic scanner says random misfires on cyls 5-8 but I dont think they are firing at all.
Yes, I plan to do compression test first.
Thanks

I checked compression on driver side and all cylinders are in good condition. Still getting DTC codes P0205- P0208 , P0300 and P0305-308. Cam timing is also good.

Checked compression and all cylinders looked good. Apparently, all the injector plugs on the driver side were loose. I was just not familiar with how tight they had to be. She runs good now!
